Read case study

I don't code features. I build products.

Before I touch the code, I ask one question: what's the impact for the user and the business? If the answer isn't clear, I dig until it is.

I ship fast, but I don't leave landmines behind. Clean code, tested, that your team can pick up without a manual.

When I join a team, I read the codebase before proposing anything. I learn how you work before suggesting how I would.
